The U.S. Space Administration issued an emergency directive to inspect 2,000 Boeing aircraft.

According tomedia reports, local time on the 24th, the U.S. aviation safety regulator issued an emergency airworthiness directive, requiring about 2,000 Boeing aircraft to be inspected. The planes have been grounded due to weak demand for flights during the New Crown outbreak.

The U.S. Space Administration issued an emergency directive to inspect 2,000 Boeing aircraft.

A spokesman for the Federal Aviation Administration reportedly said the agency issued emergency airworthiness instructions for U.S.-registered Boeing 737NG and 737Classic to check the aircraft’s air check valves for damage that caused the twin engines to fail.

The directive applies to aircraft that do not operate for seven days or more, the report said. Earlier, when inspectors took the plane out of the warehouse, they found damage to the air check valve on the plane.

The Federal Aviation Administration says that if an inspection finds damage to the plane’s air check valve, it must replace the valve before the plane is put back into service.
